How this vulnerability can be exploited
This issue can be reached with local access to the system, attack complexity is low, an attacker needs administrative privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality low, integrity high, availability high.
CVSS metrics in full
The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:H/A:H
- Attack vector: Local — a local account, shell or session on the host is needed.
- Attack complexity: Low — the attack works reliably, with no preparation.
- Privileges required: High — administrative rights are needed first.
- User interaction: None — nobody has to be tricked into anything.
- Scope: Changed — a successful attack reaches components beyond the vulnerable one.
- Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
- Integrity impact: High — total loss, or loss the attacker controls.
- Availability impact: High — total loss, or loss the attacker controls.
